TECHNICAL FIELD

Various embodiments of the present invention generally relate tomedication management. More specifically, some embodiments of thepresent invention relate to systems and methods for portable managementand monitoring of an eye drop medication regiment.

BACKGROUND

Approximately thirty percent of medication prescriptions are neverfilled. In addition, approximately fifty percent of medications forchronic disease are not taken as prescribed. This lack of adherence hasdramatic effects on health. Non adherence has been estimated to cost theU.S. health care system $200 billion annually. In ophthalmology, theproblem of noncompliance is particularly significant in the managementof chronic conditions such as glaucoma where a strict adherence to themedication plan is vital for preventing visual loss and blindness.Almost seventy-five percent of patients admit to some form ofnoncompliant behavior, over thirty percent do not fill theirprescriptions, and nearly fifty percent discontinue prescribed dropswithin six months.

While forgetfulness is one barrier to medication adherence, it is notthe only barrier. In addition, taking the medication at the wrong time,stopping too early or taking the wrong dose also represent other seriousbarriers. Unfortunately, there are no effective systems for managingadherence to a medication plan which can be vital for preventing visualloss and/or blindness.

The term “module” refers broadly to a software, hardware, or firmware(or any combination thereof) component. Modules are typically functionalcomponents that can generate useful data or other output using specifiedinput(s). A module may or may not be self-contained. An applicationprogram (also called an “application”) may include one or more modules,or a module can include one or more application programs.

FIG. 1 illustrates an example of a medication management device inaccordance with one or more embodiments of the present invention. Asillustrated in FIG. 1, the medication management device provides ajacket or expansion pack 100 to enclose a bottle of eye drops withinopening 110. Jacket 100 can include a wing pressure mechanism 120, atactile sensor 130, a drop sensor 140, and an electronic modulecompartment 150. Wing pressure mechanism 120 provides a mechanism forsecuring a bottle within opening 110 of jacket 100. In otherembodiments, other mechanisms may be used. For example, inserts ofdifferent sizes may be sized to fit securely within opening 110 ofjacket 100, and at the same time, provide a smaller opening for securingthe bottle. In other cases, different materials may be used to linejacket 100 that are flexible enough to allow for insertion of a bottle.

Tactile sensor 130 can be used to provide a touch input interface (e.g.,to detect the finger of a user). The user's touch can thenactivate/deactivate (i.e., turn on-off) the device. In some embodiments,the sensors can also detect and record other types of data such as pulseand heart rate. Drop detector sensor 140 can detect when a drop ofliquid leaves the bottle. Drop sensor 140 could be an optical (e.g.,LED/phototransistor) sensor capable of detecting if a drop has beenreleased from the bottle. In these cases, when a drop is released fromthe bottle, the drop will refract a beam and produce a signal on theoutput. Drop sensor 140 may be placed at the top of the expansion packand could be activated only in a specific position of the bottle toconserve power.

Electronic module compartment 150 can house one or more modules and/orcomponents (e.g., processors, communication devices, integratedelectronics, memory storage devices, batteries, etc.) of the medicationmanagement device. For example, in some embodiments, electronic modulecompartment 150 can include a gesture recognition module. The gesturerecognition module can be used for detecting and providing the hand andbottle motion and position. In order to avoid false and unwanted motionmeasurement, in some embodiments, the gesture recognition module may beactivated only when the tactile sensors detect the user's fingers'touch.

As another example, a wireless communication module can be used to sendand receive data to and from a computer and portable communicationdevices. An embedded controller module can include signal preprocessingelectronics. Still yet, the device may include Bluetooth wirelesstechnology to send and load data to a mobile device or computer.

In some embodiments, jacket 100 may have integrated electronics andcomponents embedded throughout. As illustrated in FIG. 2, electronicmodule compartment 150 can be removable from jacket 100. As a result,some embodiments provide for a plurality of jackets, each havingopenings of different sizes and lengths to hold different sized bottles.The jackets can be removed and interchanged with the electronic modulecompartment.

FIG. 3 is a side view of a user tilting a portable medication managementdevice 310 in accordance with some embodiments of the present invention.Once a bottle is placed within the device and a user begins to interactwith portable medication management device 310, various subsystems canbe activated for tracking the user's activity. For example, when theuser interacts (e.g., touches, moves, etc.) with the device, varioussensors (e.g., drop sensors) can be activated. The user tilts portablemedication management device 410 to distribute eye drops 430 from bottle420, as illustrated in FIG. 4.

FIG. 5 is a flowchart illustrating a set of exemplary operations 500 forusing a medication management device in accordance with some embodimentsof the present invention. As illustrated in FIG. 5, detection operation510 uses one or more tactile sensors to detect a touch from the user.The tactile sensors may be used to produce tactile sensor data. The datacan include information regarding amount of pressure on each sensor,length of touch, touching patterns, and/or other information. Upondetection of a touch from the user, the tactile sensor data can be usedto activate a motion-sensing subsystem within the device. In someembodiments, for example, the motion-sensing subsystem may only beactivated when a touch lasting more than a predetermined length of time(e.g., one second) is detected.

As the user moves the bottle during movement operation 530, the motionsensors are capable of detecting the bottle's motion and activating adrop sensor during activation operation 540. In some embodiments, if nomovement is detected within a certain amount of time (e.g., tenseconds), the motion detectors may be deactivated. Once the drop sensoris activated, monitoring operation 550 determines if a drop has beenreleased from the bottle. Data (e.g., number of drops, time, date, etc.)may then be transmitted to a medication adherence system or acommunications device for processing and/or tracking.

FIG. 6 is a flowchart illustrating a set of exemplary operations 600 fordetermining if an eye drop has been released in accordance with someembodiments of the present invention. As illustrated in FIG. 6, one ormore tactile sensors can be used to detect user interaction with themedication management device during detection operation 610. Inaccordance with various embodiments, the tactile sensors may be activelymonitoring for input from the user. In other embodiments, the tactilesensors may be a mechanical switch or button that requires a specifictype of pressure, motion, or interaction in order to trigger a detectionevent having a set of tactile data. This data can be used to activateone or more drop sensors during activation operation 620. Determinationoperation 630 then determines if the drop sensor detects a drop beingreleased from the bottle. Information regarding the drop (e.g.,medication type, time of day, date, etc.) can then be transmitted to amedication adherence system during output operation 640. Outputoperation 640 may send updates automatically on a predetermined scheduleor upon detection of an event. In some cases, wireless transmissions(e.g., cellular, Bluetooth, etc.) can be used to transmit the data.

FIG. 7 is a flowchart illustrating a set of exemplary operations formeasuring medication adherence and user vitals in accordance with someembodiments of the present invention. As illustrated in FIG. 7,detection operation 710 uses one or more tactile sensors to detect atouch from the user. The tactile sensors may be used to produce tactilesensor data. As discussed above, the data can include informationregarding amount of pressure on each sensor, length of touch, touchingpatterns, and/or other information. Upon detection of the touch from theuser, the tactile sensor data can be used to activate a motion-sensingsubsystem within the device during motion-sensing activation operation720.

As the user moves the bottle during movement operation 730, the motionsensors are capable of detecting the bottle's motion and activating adrop sensor during activation operation 740. Once the drop sensor isactivated, monitoring operation 750 determines if a drop has beenreleased from the bottle. Drop data (e.g., number of drops, time, date,etc.) may then be transmitted to a medication adherence system or acommunications device for processing and/or tracking.

If motion-sensing operation 720 does not detect any movement of thebottle by the user, holding operation 770 determines if the usercontinues to hold the one or more tactile sensors (e.g., for more thanfive or ten seconds). Once a holding threshold has been exceeded, apulse rate measuring algorithm may be activated during pulse rateactivation operation 780 to measure the user's pulse rate, heart rate,or even blood chemistry. The pulse rate data can then be transmitted toanother device and/or monitoring system.

Embodiments of the present invention include various steps andoperations, which have been described above. A variety of these stepsand operations may be performed by hardware components or may beembodied in machine-executable instructions, which may be used to causea general-purpose or special-purpose processor programmed with theinstructions to perform the steps. Alternatively, the steps may beperformed by a combination of hardware, software, and/or firmware.
